Dan, in your example graphic at the top of this thread, the bass track is Green, so it is a RealTrack. Some RealTracks (those with an underscore) have notation associated with them, but it isn't that notation that is playing; all the notation shows is an after-the-fact approximation of what was played. Thus editing it does nothing. You can also see which RealTracks have notation by looking at the column N near the far right in the RealTracks picker.

Just a note triggered by Noel's mention above of "freezing" a track. In the case of tracks you CAN edit, the most common cause of confusion in questions here is that someone forgets a track is frozen and wonders why the change isn't being heard. Unfreeze first, but unless it is the Melody or Soloist track, be sure to freeze again immediately after the edit, before regeneration changes it entirely.

Finally, it is now technically possible to do some editing on an audio track, using Melodyne Editor. However, doing so is a painstaking process that I would only recommend as a last-ditch save.
